We use the ab initio Bethe ansatz dynamics to predict the dissociation of one-dimensional cold-atom breathers that are created by a quench from a fundamental soliton. We find that the dissociation is a robust quantum many-body effect, while in the mean-field (MF) limit the dissociation is forbidden by the integrability of the underlying nonlinear Schrödinger equation. The analysis demonstrates the possibility to observe quantum many-body effects without leaving the MF range of experimental…

Nonlocal Pair Correlations in a Higher-Order Bose Gas Soliton.
The truncated Wigner and positive-P phase-space representations are used to study the dynamics of a one-dimensional Bose gas and show that there are large nonlocal correlations and nonclassical quantum entanglement.
Excitation Modes of Bright Matter-Wave Solitons.
It is shown that a deliberate mismatch of quench parameters allows for the excitation of breathing modes of the emerging soliton and for the determination of its breathing frequency as a function of atom number and confinement.
Interplay of solitons and radiation in one-dimensional Bose gases
We study relaxation dynamics in one-dimensional Bose gases, formulated as an initial value problem for the classical non-linear Schr\"{o}dinger equation. We propose an analytic technique which takes
Quantum coherent states of interacting Bose-Fermi mixtures in one dimension
We study two-component atomic gas mixtures in one dimension involving both bosons and fermions. When the inter-species interaction is attractive, we report a rich variety of coherent ground-state
Dynamics of nonlinear Schrödinger breathers in a potential trap.
We consider the evolution of the 2-soliton (breather) of the nonlinear Schrödinger equation on a semi-infinite line with the zero boundary condition and a linear potential, which corresponds to the
Splitting of nonlinear-Schrödinger-equation breathers by linear and nonlinear localized potentials
We consider evolution of one-dimensional nonlinear-Schr\"odinger (NLS) two-soliton complexes (breathers) with narrow repulsive or attractive potentials (barrier or well, respectively). By means of

Quantum Fluctuations of the Center of Mass and Relative Parameters of Nonlinear Schrödinger Breathers.
The breather dissociation time is confirmed to be within the limits of current cold-atom experiments, for macroscopic N, and fluctuations of soliton masses, phases, and positions are evaluated and may have experimental implications.


One-dimensional Bose gas dynamics: Breather relaxation
One-dimensional Bose gases are a useful testing-ground for quantum dynamics in many-body theory. They allow experimental tests of many-body theory predictions in an exponentially complex quantum
Higher-order quantum bright solitons in Bose-Einstein condensates show truly quantum emergent behavior
When an interaction quench by a factor of four is applied to an attractive Bose-Einstein condensate, a higher-order quantum bright soliton exhibiting robust oscillations is predicted in the
Metastability versus collapse following a quench in attractive Bose-Einstein condensates
We consider a Bose-Einstein condensate (BEC) with attractive two-body interactions in a cigar-shaped trap, initially prepared in its ground state for a given negative scattering length, which is
A new language, Opt, is proposed for writing these objective functions over image- or graph-structured unknowns concisely and at a high level and automatically transforms these specifications into state-of-the-art GPU solvers based on Gauss-Newton or Levenberg-Marquardt methods.
